Patent PT-1033398-E (PT)
Inventor: PETERS KENNETH D
IPC: C10G65/00
Filed: 1999-03-04
Abstract: The operation of multistage catalytic hydrocarbon conversion system in which hydrocarbons flow serially through at least two reaction zones is improved by using staggered by-passing of a portion of the change to each zone such that the first zone processes only a first portion of the feed and the second zone processes the remaining portion of the feed and at least a portion of the effluent from the first zone. Where three reaction zones are used, processing of the effluent stream from the first reaction zone is split between the second and third reaction zones so that a portion of the charge to each zone always is directed around the zone and processed in the next reaction zone. One portion of the effluent stream is combined with hydrocarbons that bypassed the first reaction zone, and the combined stream is passed to the second reaction zone. The other portion of the first reaction zone effluent stream and at least a portion of the effluent stream of the second reaction zone are passed to the third reaction zone. This invention is applicable to processes where the first and second reaction zones are susceptible to pinning in that this invention decreases the mass flow through the first and second reaction zones while nevertheless maintaining high hydrocarbon conversion capacity. <IMAGE>
Patent PT-1062348-E (PT)
Inventor: LEUNG SHUI-ON
IPC: C12N15/55
Filed: 1999-03-11
Abstract: Recombinantly-produced Onconase molecules and fusion proteins containing the same are disclosed. The recombinantly-produced Onconase molecule has the sequence of native Onconase, retains the proper folding of native Onconase and has cytotoxic activity similar to that of Onconase purified from oocytes of Rana pipiens. cDNA coding for Onconase is extended by one triplet which codes for N-formyl-methionine. When expressed recombinantly, the mutant Onconase has N-formyl-methionine as the N-terminal amino acid, and glutaminyl as the penultimate N-terminal residue. Following expression, the N-formyl methionine residue is cleaved and the penultimate glutaminyl residues are cyclized to produce Onconase with an N-terminal pyroglutamate residue, and hence the same structure and function as native Onconase.

Filed: 1973-02-07
Abstract: 1362751 Treating tobacco IMPERIAL CHEMICAL INDUSTRIES Ltd 5 Feb 1973 [2 March 1972] 9808/72 Heading A2C The flavour of tobacco when smoked is enhanced by catalysed thermal degradation of the tobacco at a temperature of 100C to 300C until the weight of degraded material is less than 90% of the weight of the original tobacco. Preferred catalysts are strong acids or their salts with weak bases, ammonium sulphamate being particularly preferred. Alkaline catalysts may also be used, but in this case the degraded tobacco should be freed from the catalysts before smoking. In the examples, various kinds of tobacco were degraded using either ammonium sulphamate or sulphuric acid as catalysts and the degraded tobacco was ground and slurried with sodium carboxymethyl cellulose, glycerol, citric acid, potassium citrate and calcium carbonate and the slurry was cast to form a sheet.

Patent IE-800256-L (IE)
Title: Method and system for producing and transporting natural gas
IPC: E21B43/00
Filed: 1980-02-11
Abstract: Natural gas taken from a gas well is loaded continuously and at a preselected, generally uniform rate into a movable separate pressure vessel means until such is filled with a discrete batch of natural gas at a pressure in excess of 800 psia, whereupon it is replaced with another separate pressure vessel means, with no interruption of gas flow. The filled, movable vessel means is then transported to an off-loading terminal. Well shock is thus controlled, and maximum natural gas recovery obtained. A generally uniform flow rate is obtained by a regulating valve, when well head pressure exceeds about 800 psia, and by a compressor when the well head pressure is below such value.

Title: Plastics screw cap openable as crown cork
IPC: B65D41/04
Filed: 1978-03-21
Abstract: In a stopper arrangement for bottles of the type having an externally threaded neck closable by a synthetic plastic screw cap, the screw cap has an approximately cylindrical internally threaded wall part which is closed by an upper lid surface. The screw cap is so dimensioned and configured, and is formed of such an elastic plastic material, that the cap can be removed by unscrewing, or can be removed by a conventional crown cork opener. In either case, the cap can be used to re-close the bottle, since it is specially constructed so as not to be destroyed if removed by a crown cork opener. Important features of the screw cap involve the number of threads, the pitch angle of the threads, the thread depth, the thickness of the cylindrical wall part, the provision of a protruding section engageable by the lifting portion of a crown cork opener, the distance between the lid surface and the protruding section, and the elasticity of the plastic material considered in conjunction with the dimensions and configuration of the cap. The inner side of the lid surface preferably is formed with a sealing member which extends into the bottle opening.
